Flat-Earthers are back: 'It’s almost like the beginning of a new religion'
www.theguardian.com/science/2016/jan/20/flat-earth…
“YouTube user TigerDan925 shocked his 26,000 followers recently by conceding a shocking point: Antarctica is a continent. It’s not, as he previously thought, an ice wall that encircles the flat disc of land and water we call earth.”

When I stand at the water's edge and look out over the ocean, how far away is the horizon?

“One of the funniest things about the ocean is the fact that its surface is curved. We tend to think about water forming large flat sheets, but the surface of a large body of water is not actually flat at all -- it follows the curvature of the Earth.”

    "Your move Bob" Must've been the best thing I've ever heard

    "I don't see it, so it isn't there." Don't kids loose that mentality around the age of 4?
  • So just because we can't see the curve there must be no curve. Well, i've never seen a flat earther's brain, so...
  • If flat-earthers really don't believe us, then they should go and find the edge. I'm not joking, if they're serious, and want to show us the truth, as they say; then they should take a picture of the edge then show it to us. Or if not, the people who know the earth is round should make the live documentary of riding a ship and continue to go forward if there is an edge or would just be back where it started, since flat-earthers don't believe in live space documentaries

    Flat Earthers claim to have members around the globe EDIT: I'm not going to question why this has 300 likes

    Why is this a conversation..... Society should be ashamed...

    It's funny when flat Earthers tell us to trust our observations and common sense. My observations tell me that time zones and sunsets, which can't both happen at once on a flat Earth, both happen at once, and common sense tells me that a conspiracy dating back 2K years that every scientist, travel agency, government, navigator, pilot, and mapmaker ever has been in on, without a single one of them telling the truth, is impossible.

    I doubt B.O.B thinks the earth is flat; he just knows that by pretending he's a conspiracy theorist he'll get tons of free coverage from people complaining. And he was right :/

    If the earth was flat. You should be able to stand on top of a large building or mountain and see the entire earth with a telescope

  • @wavyiann9788
    There’s an 24/7 live stream of earth.... it’s round 🤦🏽‍♂️
  • Next up from DNews: How we know that grass is green Bonus episode: How we know that water is wet
  • who knew the people in the Ancient times are smarter than some people in this modern world
  • The weirder thing than flat earth is. The advertisements in youtube are louder that the videos themselves.

    Flat earthers: fake! They used CGI in 350BC Flat earthers: we did a far better science experiment. We took a level on an airplane and the bubble didn’t move. Flat earthers: the moon is a spot light. Wait, no it’s a hologram. Everyone with half a brain: I can see the moon is a solid mass and round with my telescope. Flat earthers: fake! You work for nasa: the telescope has a fish eye lens. Did I miss anything lol
